“There Is A North”: Fugitive Slaves, Political Crisis, And Cultural Transformation In The Coming Of The Civil War, Kellen Heniford

Civil War Book Review

John Brooke shows that "between 1850 and 1854, white northerners experienced fundamental political and cultural shifts that pushed enough of them towards an active antislavery politics that a conflagration with the slaveholding South became almost inevitable."

Tar spot on corn, caused by the fungus (Phyllachora maydis Maubl. [Phyllachorales: Phyllachoraceae]), is an emerging disease in the United States. In 2018 and 2019, significant but localized epidemics of tar spot occurred across the major corn producing region of the Midwest. After being first detected in 2015, tar spot was detected in 135 and 139 counties where the disease was not previously detected in 2018 and 2019, respectively, and is now established across 310 counties across the United Sates. Foliage with signs (stromata) of P. maydis and symptoms of tar spot were collected from 128 fields in 2018 and …

Corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), has emerged as an injurious insect pest to hemp, Cannabis sativa L., a crop newly reintroduced to the United States. Growing hemp presents a potential alternative economic opportunity for farmers but can be challenging with a market that is unstable and just developing. One of the most notable production challenges is managing corn earworm, an insect pest that is particularly damaging when it feeds on flower buds produced in cannabinoid varieties, creating extensive bud tunneling and wounds that allow entry of pathogens that can aid development and presence of bud rot. Damage to …

A Notable Bully: Colonel Billy Wilson, Masculinity, And The Pursuit Of Violence In The Civil War Era, Lorien Foote

Civil War Book Review

With his “flair for storytelling,” Cray gives vibrancy to “scholarly conclusions of gender historians regarding the role of violence in nineteenth-century manhood,” Reviewer Lorien L. Foote writes. Foote agrees with Cray’s contention that Wilson’s story is one “’worth knowing,’” and she contends herself that “the story as Cray tells it, is worth reading.”

Going Feminine: Identifying How And When Female Candidates Emphasize Feminine And Masculine Traits On The Campaign Trail, Nichole M. Bauer, Martina Santia

Faculty Publications

Female candidates face a messaging challenge. There is a strong association between masculinity and political leadership. Stressing masculinity can result in a likability backlash for female candidates often seen as lacking feminine qualities, such as warmth. Preventing a likability backlash by highlighting feminine qualities can also harm female candidates. Current scholarship offers conflicting conclusions about how female candidates balance these gendered challenges. We fill this empirical and theoretical gap with a trait-balancing theory clarifying how and when female candidates use feminine and masculine traits to manage competing expectations. We use original data merging information on candidate advertising strategies across three …

Association Between The Consumption Of Breakfast And The Recommendation Of Physical Activity And The Nutritional Status In Children, Eduardo Rossato De Victo, Gerson Ferrari, Dirceu Solé, Carlos André Miranda Pires, Timóteo Leandro Araújo, Peter T. Katzmarzyk, Victor Keihan Rodrigues Matsudo

Population and Public Health Science Faculty Publications

The scope of this article is to associate breakfast consumption (BC) with moderate to vi-gorous physical activity (MVPA) intensity and the nutritional status of children aged 9-11. The sample consisted of 432 children from São Caetano do Sul participating in the International Study of Childhood Obesity Lifestyle and the Environment. Data were collected between 2012 and 2013. The weekly BC was obtained using the self-reported method. To measure MVPA, children used ac-celerometers and were classified into two groups (< 60 versus ≥60 min/day). The nutritional status was presented by body mass index (BMI). Logistic regression models were used, adjusted for gender, age, race, parental educational level and eating score. The mean BC was 5.25 (CI95%: 5.1-5.4) days/week and the MVPA was 59.29 (CI95%: 57.3-61.7) min/day. In the total sample, 55.8% of the children did not perform ≥60 min/day of MVPA and 50.2% were overweight or obese. The daily BC was not associated with MVPA, however, it reduced the odds of children being overweight or obese (OR: 0.51; CI95%: 0.34-0.76; p=0.001). Daily BC reduced the odds of excess weight or obesity in children, though it did not increase the chances of children meeting the recommendations of MVPA. Public policies should encourage daily BC to prevent excess weight or obesity.

Executive Deviance As A Sociopolitical Force In Dismissals, Jeremy J. Foreman, Brian P. Soebbing, Chad S. Seifried

Faculty Publications

The seminal model of CEO dismissals utilizes four sociopolitical forces that operate together in determining whether a CEO will be dismissed. Missing from the sociopolitical forces of CEO dismissals is executive deviance. We propose the inclusion of executive deviance as the fifth sociopolitical force in CEO dismissals, which is not limited to the deviant actions of the executive, but also the executive’s subordinates. Within the comprehensive CEO dismissal framework, the effect of executive deviance on head coach dismissals in the National Football League (NFL) from the 2000–2001 to 2015–2016 season is examined using four levels of executive deviance: (a) deviance …

Division of Basic Science Faculty Publications

The inflammatory response is an obstacle to success in both allogeneic and autologous islet transplantation. In autologous islet transplantation (AIT), however, the recipient is also the donor, permitting pretreatment of donor/recipient for a controlled duration prior to transplantation. We sought to exploit this feature of (AIT) by pretreating donor/recipients with chronic pancreatitis undergoing total pancreatectomy and autologous islet transplantation (TPAIT) to test the hypothesis that peri-transplant treatment with the FDA-approved anti-inflammatory hydroxychloroquine (HCQ) improves graft function. In this randomized placebo-controlled pilot clinical study, patients (n = 6) were treated with oral HCQ for 30 days prior to and 90 days …

Nutritional interventions are one of the most promising non-pharmacological therapeutics to attenuate aging in humans. This narrative review aims to describe the implications of moderate and prolonged calorie restriction (CR) in healthy adults without obesity that occur beyond weight loss. Areas covered: Findings from CR studies, such as the CALERIE (Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy) trials, the most rigorous trials to date examining a prolonged 25% CR, are described. The main areas covered include; changes to …

Christian Nationalism And Views Of Immigrants In The United States: Is The Relationship Stronger For The Religiously Inactive?, Samuel Stroope, Heather M. Rackin, Paul Froese

Faculty Publications

Previous research has shown that Christian nationalism is linked to nativism and immigrant animus, while religious service attendance is associated with pro-immigrant views. The findings highlight the importance of distinguishing between religious ideologies and practices when considering how religion affects politics. Using a national sample of U.S. adults, we analyze immigrant views by measuring levels of agreement or disagreement that undocumented immigrants from Mexico are “mostly dangerous criminals.” We find that Christian nationalism is inversely related to pro-immigrant views for both the religiously active and inactive. However, strongly pro-immigrant views are less likely and anti-immigrant views are more likely among …

Eat Clean And Safe Food: A Food-Based Dietary Guideline For The Elderly In South Africa, Makenzie Miller, Wilna Oldewage-Theron, Carin Napier

Faculty Publications

As the population of elderly individuals in South Africa (SA) grows, there is a need to promote the continued health of these persons as they progress through the life cycle. Food Based Dietary Guidelines (FBDGs) for the SA elderly were developed to address this need. These thirteen guidelines for the elderly collectively offer a basis of health practices that the elderly can follow to ensure that they are taking the right steps toward maintaining their health. While the guideline ‘Eat clean and safe food’ is not included in the current SA FBDGs, this recommendation is of particular importance to the …

Solopreneur Digital Ecosystems: Genesis, Lineage And Preliminary Categorization, Gabriele Piccoli, Biagio Palese, Joaquin Rodriguez

Faculty Publications

This paper traces the genesis and lineage of solopreneur digital ecosystems. These ecosystems, fostered by a digital environment that is infrastructural, combinatorial and servitized, are enabling the rise to prominence of the solopreneur. We theorize solopreneur digital ecosystems as the latest incarnation of systems beyond firm control, with digital platforms and digital marketplaces as their principal enablers. In an effort to compare them from the perspective of the solopreneur, we categorize solopreneur digital ecosystems on three dimensions: algorithmic control, commoditization, and lock-in. Our work contributes a framework that solopreneurs can use to identify ecosystems in which they can optimally invest …

Virtual Reality As A Versatile Tool For Research, Dissemination And Mediation In The Humanities, Paul François, Jeffrey Leichman, Florent Laroche, Françoise Rubellin

Faculty Publications

The VESPACE project aims to revive an evening of theatre at the Foire Saint-Germain in Paris in the 18th century, by recreating spaces, atmospheres and theatrical entertainment in virtual reality. The venues of this fair have disappeared without leaving any archaeological traces, so their digital reconstruction requires fusing many different sources, including the expertise of historians, as well as of historians of theatre and literature. In this article, we present how we have used video game creation tools to enable the use of virtual reality in three key research stages in the human sciences, and particularly, in history or archaeology: …

Fear Of Zika: Information Seeking As Cause And Consequence, James Price Dillard, Ruobing Li, Chun Yang

Faculty Publications

This study examined the relationship between information seeking and fear during the Zika-induced global health crisis. A longitudinal survey of women in the Southern U.S. (N = 306) was conducted in 2016, beginning just days after the World Health Organization declared Zika a global crisis. The data showed that time 1 fear stimulated information seeking at time 2 and that time 2 information seeking caused fear at time 3. This pattern held regardless of whether participants were pregnant or planning to become pregnant (high personal relevance) versus neither (low personal relevance). The findings are at odds with most theories of …

Characterisation Of Nano-Assemblies Inside Mesopores Using Neutron Scattering*, Yingzhen Ma, William T. Heller, Lilin He, William A. Shelton, Gernot Rother, Bhuvnesh Bharti

Faculty Publications

Adsorption of molecular and nanoscale matter in mesoporous materials is important in filtration and chromatography as well as membrane processes. However, the morphology and distribution of self-assembled structures of adsorbate formed within nanoconfined environments is largely unknown. Small Angle Neutron Scattering (SANS) with porous matrix matching the neutron scattering length density of the solvent has the potential to provide detailed information on the self-assemblies formed in pore spaces. However, analysis of such SANS profiles remains a challenge. In this study, we extend the SANS analysis method previously developed by Findenegg and co-workers to include interparticle correlations, providing a qualitative characterisation …

Deep Learning-Based Hardness Prediction Of Novel Refractory High-Entropy Alloys With Experimental Validation, Uttam Bhandari, Congyan Zhang, Congyuan Zeng, Shengmin Guo, Aashish Adhikari, Shizhong Yang

Faculty Publications

Hardness is an essential property in the design of refractory high entropy alloys (RHEAs). This study shows how a neural network (NN) model can be used to predict the hardness of a RHEA, for the first time. We predicted the hardness of several alloys, including the novel C0.1Cr3Mo11.9Nb20 Re15Ta30W20 using the NN model. The hardness predicted from the NN model was consistent with the available experimental results. The NN model prediction of C0.1Cr3Mo11.9Nb20Re15Ta30W20 was verified by experimentally synthesizing and investigating its microstructure properties and hardness. This model provides an alternative route to determine the Vickers hardness of RHEAs.

An Open-Source Code For Fluid Flow Simulations In Unconventional Fractured Reservoirs, B Wang, C Fidelibus

Faculty Publications

In this study, three magnetic ionic liquids (MILs) were investigated for extraction of four estrogens, i.e., estrone (E1), estradiol (E2), estriol (E3), and ethinylestradiol (EE2), from environmental water. The cation trihexyl(tetradecyl)phosphonium ([P66614]+), selected to confer hydrophobicity to the resulting MIL, was combined with tetrachloroferrate(III), ferricyanide, and dysprosium thiocyanate to yield ([P66614][FeCl4]), ([P66614]3[Fe(CN)6]), and ([P66614]5[Dy(SCN)8]), respectively. After evaluation of various strategies to develop a liquid-liquid microextraction technique based on synthesized MILs, we placed the MILs onto a magnetic stir bar and used them as extracting solvents. After extraction, the MIL-enriched phase was dissolved in methanol and injected into an HPLC-UV for …

Identification Of Blda As A Major Regulator Of Virulence In The Sweetpotato Soil Rot Pathogen Streptomyces Ipomoeae And Characterization Of Distinct Clostridium Sweetpotato Soft Rot Isolates, Kuei-Ting Yang

LSU Doctoral Dissertations

Streptomyces ipomoeae is the causative agent of Streptomyces soil rot on sweetpotato, a disease characterized by extensive necrosis of both adventitious and storage roots. While Streptomyces potato scab pathogens produce a phytotoxin (thaxtomin A), which is induced in the presence of cellobiose and suberin, S. ipomoeae produces a less-modified, phytotoxin (thaxtomin C), whose inducer has not been identified. To investigate transcriptional regulation of thaxtomin C production, we inserted a promoter involved in thaxtomin C synthesis upstream of the gusA reporter in an S. ipomoeae strain. Reporter gene expression was significantly upregulated in the presence of size-fractionated sweetpotato extract (SPE). The …
